Palmer shouldn't have erased anything tbh. He's a decent player but he's not someone I look at and think "Yeah, we're good now that we have him". And Shenault is simply not good so I certainly hope he isn't as involved in the offense as Hollins was. Aside from safety, our WR room is one of the weakest on the team still.
Maybe the plan is to have another season of historically low turnovers and hope Josh wins another MVP because of the talent around him?
